Mercer, formerly branded Cala, is an all-in-one platform for fashion product design and development. The core idea is to keep everything from inspiration photos and sketches to technical packs, assets and production approvals inside a single workspace, so teams stop juggling email attachments, spreadsheets and file transfer services. Generative AI sits at the center of the workflow: users describe or upload a concept, generate imagery with the built-in AI Designer tool, and refine results with text-to-image, product variations and an AI Paintbrush editor.
A distinguishing feature is Mercer's AI Influences tool, which trains a custom model on a brand's own reference imagery so new product ideas stay visually consistent with past collections. Around that design engine, the platform layers collaboration and project management: comments and measurements on creative files, task assignment with dashboard and email notifications, timelines and checklists, plus sharing through print-ready PDFs or collection links so external partners can review work without an account.
Pricing is based on monthly subscription tiers — Designer, Studio, Studio Pro and Enterprise — differentiated by AI image or credit allowances, the number of editors and access to task management, costing and manufacturing services. A key scoping detail is that only Enterprise subscriptions include actual production and manufacturing services; lower tiers are design and collaboration software only, and Mercer states that user data is not used to train its foundational models and that designs remain the property of the creator.
